Documentation improvements

[zgotsch]

The documentation is seems like it's mostly copied from the Content Record Library (Content Record DAC). This is confusing because it says things like "The main purpose of this tool is content discovery; if all skapps were to make use of this library, the end result would be a scrapable global record of all content and the popularity of that content and the skapp."

Additionally, it ends in the middle of a sentence ("This is when a user"):

The example code

import { SkynetClient } from "skynet-js";
import { UserProfileDAC } from "@skynethub/userprofile-library";

(async () => {
  // create client
  const client = new SkynetClient();

  // create content record
  const userProfileRecord = new UserProfileDAC();

  // load mysky
  const mySky = await client.loadMySky("exampleskapp.hns");
  
  // get userID
  const userID = await mySky.userID()
  
  // load DACs
  await mySky.loadDacs(userProfileRecord);

  let userProfile =await mySky.getProfile(userID);
  let userPreference =await mySky.getPreferences(userID);



 
})();

is poorly formatted and incorrect. loadProfile (and getPreferences) is not a method on mySky, but on IUserProfileDAC (userProfileRecord in the example).
